WINDOW-CLEANING CHAlR SPECIFICATION forming part of Letters Patent No.432,643, dated July 22, 1890. Application filed October 3, 1889. SerialNo. 825.888. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM M. REY- NOLDS, of New York, in the countyand State of New York, have invented certain new and useful Improvementsin \Vindow-Cleaning Chairs, of which the following is a specification.

My invention relates to chairs which are used upon the sills of windowswhen domestics are engaged in cleaning the glasses. The general purposeof such chairs is to diminish the danger attending such operation and toafford a convenient and comfortable seat for the person thus engaged andenable him freely to use both hands. Various forms of chairs of thischaracter have heretofore been devised, and the one which more nearlyresembles my invention than any others of which I am aware is that shownin the patent of Crook, No. 410,957, of September 10, 1889, and myinvention contemplates certain improvements upon that chair.

The subject-matter claimed is hereinafter specified.

In the accompanying drawings, Figure 1 is a perspective view of a chairembodying my improvements; Fig. 2, a side elevation indicating the chairin position upon a windowsill; Fig. 3, an enlarged view of one of thekeepers or straps with which the chair is interlocked when in place, andFig. 4 a detail view of the end of one of the braces which support thechair-bottom; Fig. 5, a detail perspective View of one of thechair-bottom hooks; Fig. (3, a side elevation showing bracerods runningfrom the sides of the chair-back to the window-frame; Fig. 7, a planshowing the same matter; and Fig. 8 is a view similar to Fig. 6, butshowing a high-back chair.

The bottom of the chair A is preferably of 'the rectangular shape shown,and it is provided with a back bow A and side braces a of any suitableconstruction. The braces or supports B B are applied to the back bow atb and to the rear edge of the chair-botto1n at b, and are then curvedinwardly, as shown, and their lower ends formed with rectangular notchesor seats D which embrace the corner of the sill when the chairis inposition. The braces are preferably formed with a strengthening-web band maybe cast in one piece of malleable iron, or otherwise constructedof suitable material. At the front of the chair, and preferably at twopoints, hooks O are se cured. They each consist of two horizontal plates0, the upperone being let into a counter sink in the face of theehair-bottom and the lower one lying against the under face of thechair-bottom, and a hook c projecting from the front of the chair andformed with a curved outer face. Upon the sill straps or keepers D arerigidly secured by screws or otherwise, and the under faces of thehorizontal parts of the keepers are preferably curved to conform to theinterior faces of the hooks.

In placing the chair in position the chair bottom is held verticallywith the back projecting into the window, and the hooks Care inserted inthe keepers D and the chair turned outwardly until the feet 11 of thebraces B rest upon and embrace the corner of the sill. I preferably soarrange the braces that the chair-bottom shall have an inclinationinwardly toward the window. This relieves the keepers and hooks of aportion of the strain and gives the body of the person a tendency towardthe direction of safety. Since the braces B extend from. the extremerear edge of the chair back and bottom to the sill, the weight of theperson occupying the chair will be thrown directly upon the edge of thesill, and there can be no tendency for the front edge of thechair-bottom to tilt upwardly and throw a strain upon the hooks andkeepers. The shape and location also of the braces B are such that ifthe person occupying the chair should lean back, so as to throw hisweight upon the back bow A, there would be but a slight tendency of thefront edge of the chair to tilt upwardly. The main strain would beoutwardly about in line with the chair-bottom, and the hooks and keepersare best adapted to resist a strain in that direction. This result ispartly due, as above mentioned, to the shape and location of the braces,and also to the fact that the vertical faces of the notches in the endsof the braces lie against the vertical face of the sill.

In order to protect the edge of the sill from abrasion or scratches, Ipreferably line the seat or notch b with felt, rubber, vulcanized fiber,or other suitable material at.

By providing two hooks and keepers and two braces B, so that near eachside of the chair a brace, hook, and keeper shall be in line, I avoidtorsional strain, and thereby further increase the durability and safetyof the chair.

As shown in Figs. 6 and 7, rods E may be connected or pivoted at eachside of the chair, preferably at the ends or sides of the back bow, andhave their hooked ends engage eyes F, secured to the sides of thewindow-frame. This affords a further measure of safety, and, in fact,makes the occupant of the chair absolutely secure. I may also, as shownin Fig.

8, make high-back chairs specially adapted for standing, so that theoccupant may readily and Without fear reach the upper sash or upperparts of the window-frame. In this case I also provide brace-rods E andeyes F in the sides of the window-frame.

I claim as my invention 1. The combination, with a chair-bottom anddevices, as O D, for connecting it with the sill, of a brace or supportbolted to the chairbot-tom and to the back bow and adapted to rest uponand embrace the corner of the sill.

2. The combination, substantially as set forth, of the chair-bottom andback bow, a brace B, secured directly to the back bow and chair-bottomand having a seat or notch for embracing the corner of the sill.

' 3. The combination of a chair-bottom and devices for connecting itwith the sill, of a support or brace B, connected with the chairback andthe rear of the chair-bottom and eX- tending inwardly under thechair-bottom, its foot being formed with a notch or seat for embracingthe corner of the sill.

4. The combination, substantially as set forth, of an ordinarychair-seat having a back, devices for removably connecting the seat ofthe chair with the window-sill, a support adapted to rest upon the outerpart of the sill to sustain the chair-seat, and braces swiveled to thesides of the chair-back and adapted to engage eyes or catches on thesides of the window-frame.

5. The combination, substantially as set forth, of the chair-bottom,devices for connecting it to the sill, a high chair-back, braces orsupports connected with the chair-back and rear of the chair-bottom andadapt-ed to rest upon the outer part of the sill, and bracerodsconnected with the sides of the chairback and adapted to engage eyes orcatches on the window-frame.

In testimony whereof I have hereunto subscribed my name.
